Correct English to German Translation for the Equipment?
 

Please, quote message and correct me if I'm wrong...Tnx!:salute:

External Equipment - Externe Geräte
Stern Buoyancy Tank - Hintere Luftkammer
Port Propulsion Transmission - Backbord Antriebsübertragung
Electric Engine Compartment - E-Maschinenraum Abteilung
Torpedo tubes - Torpedorohr
Variable ballast Tanks - Auftrieb Regel Tanks
Aft.Quarters(where bunks for petty officers are) - ??
Main Ballast tank 3 - Hauptballasttank 3

No Germans online tonight? :D

You got most of them right:

External Equipment - Externe Geräte (UZO, Radar etc.) or Externe Ausrüstung (includes weapons)
Port Propulsion Transmission - Backbord Antriebswelle
Electric Engine Compartment - E-Maschinenraum
Torpedo tubes - Torpedorohre (plural), "Bugtorpedorohre" -> the 4 tubes in the bow, Torpedorohr (singular), "achteres Torpedorohr" -> the stern tube
Aft.Quarters(where bunks for petty officers are) - Unteroffiziersraum (abbr.: U-Raum)

Typ VII bow to stern:

Bugraum, Offiziersraum, Horchraum, Funkraum, Zentrale, Unteroffiziersraum, Kombüse, Maschinenraum, E-Maschinenraum

I don't know how specific you want to be with the nomenclature of the various compartments inside a submarine (http://www.uboatarchive.net/Manual.htm page 4 for reference)

Main Ballast tank 3 - "Hauptballasttank 3" is a good translation, the technical term is "Tauchzelle 3", "Tauchzellen" are flooded to make the sub dive. The Typ VII had one "Tauchzelle" (No. 3) inside the pressure hull and one in the bulge on each side outside the pressure hull (No. 1+5).

Stern Buoyancy Tank - Hintere Luftkammer, not sure which compartment you are referring to here. Typ VII had two "Negative buoyancy tanks" -> "Untertriebszellen" that were flooded when the sub was surfaced to facilitate crash diving and blown out at a depth of 10-15 m.

Variable ballast Tanks - Auftrieb Regel Tanks, not sure again.
"Regulating tank" - > "Regelzelle" (were used to fine-tune buoyancy, could hold air or water, No. 2a/2b) or "Regelbunker" (could hold air, water or fuel).

Some other compartments:

Aft./ Forw. trim tank -> achtere / vordere Trimmzelle
Torpedo compensation tank -> Torpedoregelzelle

HTH

TY very much Skidman!

I need something wich will reffer to propulsion transmission, not to propeller it self... Like Tiefenruderübertragung and Tiefenruder

This is from Type VIIC manual...
Stern and bow buoyancy tanks.
The aft and forward parts of outer shell are constructed as stern and bow buoyancy tanks and are used to dampen longitudinal pitching of the boat. Both tanks have flood slits and one vent valve each.
Page 38

Manuall:
To compensate for changes of weight caused by consumption of provisions, fuel oil, munitions, different number of crew and buoyancy changes due to leakage, regulating tanks 2 port and stb. are provided. They are located on both sides of pressure hull near the control room and are pressure-tight. The amount of water inside the tanks is readable by means of water level indicators or measurable by means of an air pressure gauge. The regulating tanks are connected to the drainage installation in control room and can be drained by main drain pump, auxiliary drain and trim pump as well as by means of compressed air. Page 38


Here are few pictures that could help...

Note that I have already change:

Hint. Quartalen to U-Raum,
Externe Geräte to Externe Ausrüstung,
Hauptballasttank 3 to Tauchzelle 3,
Auftrieb Regel Tanks to Regelzelle...

You're welcome.

Right. The crankshaft (->Kurbelwelle) of the Diesel engine and the electric motor shaft can be coupled to the propeller shaft (-> Propellerwelle) as part of the drive shaft (-> Antriebswelle). So maybe you are looking for a term that refers to the shaft coupling (-> Wellenkupplung).

That's a tough one. I have never heard of those tanks and I have hurt my brain trying to figure out how they work (inertia of moving masses? I just don't get it).

-> Regelzelle(n)

Exactly! :up:

Check out this video (06:15)...It's american sub but principle is surly the same same... http://www.youtube.com/watch?v=acu8JTzmF6M

Does Hintere Luftkammer have any sense at all? Do you know some other , more technical term?

"Luftkammer" doesn't make sense, because the tank can hold air or water. You could use "vorderer / achterer Ausgleichstank" or "vordere / achtere Ausgleichszelle" a generic term, that at least reflects the functionality of the compartment.

OK, but this buoyancy tank is emptied actively to facilitate dynamic depth reduction (get the bow up).

This really makes my brain ache :/\\!!: A open system with slits near the bottom of the compartment with a pressure excess valve and a vacuum valve near the top would be useful to "dampen longitudinal pitching": Intake of water when the slits are beneath the surface -> increase of mass before the next upward movement. Loss of water, when the slits are above the surface -> decrease of mass before the next downward movement. But a tank with slits and a vent valve??? Nah, I give up :06:

No need for brain ache, you really helped me a lot Skidman! :up:

It will be "vordere / achtere Ausgleichszelle" than... It describe function correctly and,for the best, it sounds so...German!:D I like it!
